Message from Prof. Okabe

Our Environmental Biotechnology group in Graduate School of Engineering at Hokkaido University mainly focuses on complex microbial ecosystems in wastewater treatments and microbial energy productions, including an anaerobic ammonium-oxidizing (Anammox) process and microbial fuel cells (please visit our "Research activity" on this home page). We are also developing a novel bioassay to evaluate the water safety by using DNA microarray technology (i.e., Toxicogenomics). The primary goal of our research and education program is to train students to use interdisciplinary approaches in the study of environmental biotechnology that lead to a more comprehensive understanding of the importance of our environment and human health. I strongly encourage interested students to contact us if you are interested in working and studying with us. Our Graduate School of Engineering offers the English Engineering Education Program or the e3 program (http://www.eng.hokudai.ac.jp/e3/), in which MEXT scholarships are available.

Offering for Ph.D. candidate scholarships

The laboratory for water quality control engineering has an opening for Ph.D. candidate scholarships. This laboratory has focused on safe and efficient usage of water resources, complex microbial ecosystems in wastewater treatment, and microbial energy production. Among them, followings will be the main topics for new members.

1. Development of a novel bioassay to evaluate the water safety by using DNA microarray technology
2. Elucidation of the biofilm formation mechanisms in water environment
3. Microbial source tracking with high accuracy by using multiple indicators
4. Fate of pathogenic viruses in water environment

Please contact the following e-mail address if you are interested in working with us.
